Product Description

The Mishimoto MMICP-DMAX-06CBK Cold-Side Intercooler Pipe and Boot Kit is engineered to replace the restrictive stock cold-side intercooler plumbing on 2006-2010 GM 2500HD and 3500HD pickups equipped with the 6.6L Duramax LBZ or LMM engines. By swapping to mandrel-bent aluminum piping with a larger 3.5" diameter, airflow is significantly improved, boosting charge air efficiency and reducing exhaust gas temperatures (EGTs) under load - all without requiring additional tuning.

This direct-fit kit includes high-quality Mishimoto DuraCore™ silicone boots that resist heat, pressure, fuel, and oil better than typical silicone, paired with constant-tension T-bolt clamps for reliable sealing. Installation is straightforward with no cutting or modifications needed, making this an ideal performance and durability upgrade for owners looking to enhance the reliability and performance of their Duramax's charge air system. Backed by Mishimoto's limited lifetime warranty, this cold-side intercooler pipe kit is a solid choice for both street and heavy-duty diesel applications.
